[As we continue on to the next episode, April, Casey the Turtles and everyone we saw buried Splinter in April's farm, where the Kraang invasion started in season 3, pay their final respects at Splinter's grave. Then, one by one, everyone walks away excluding the four Turtles. Leo is the last one to leave. Wandering alone in the woods near the farmhouse, Leo is calmly meditating at a riverbank. The wind whistles and then a voice speaks.]
Leonardo. [Leo gasps, revealing that it was Splinter's Spirit.] Do not fear me, my son.
Sensei, is it really you or am I... dreaming this?
You are not dreaming. I have attained a higher spiritual plane of existence. Passing into death, we merge with the whole of life. We become one with nature, in all of the universe. Even with you.
I can't go on without you, Father.
You must, Leonardo. You are the sensei now. Your brothers need you. Karai needs you. Shredder is still alive.
What!?
You must end this, Leonardo.
I don't know if we're strong enough, Sensei. Sensei?
[As the wind whistles again, Leo watches some flower petals fly over his head and soar up towards the shining sun breaking through the clouds, before putting on his empty, white eyes, Leo decides to lead the Hamato Clan and finish off their long feud with Super Shredder once and for all.]
